4 years agodrm/i915: Tighten atomicity of i915_active_acquire vs i915_active_release
Chris Wilson [Sun, 26 Jan 2020 10:23:43 +0000 (10:23 +0000)]
drm/i915: Tighten atomicity of i915_active_acquire vs i915_active_release

As we use a mutex to serialise the first acquire (as it may be a lengthy
operation), but only an atomic decrement for the release, we have to
be careful in case a second thread races and completes both
acquire/release as the first finishes its acquire.

Thread A Thread B
i915_active_acquire i915_active_acquire
  atomic_read() == 0   atomic_read() == 0
  mutex_lock()   mutex_lock()
  atomic_read() == 0
    ref->active();
  atomic_inc()
  mutex_unlock()
  atomic_read() == 1
i915_active_release
  atomic_dec_and_test() -> 0
    ref->retire()
  atomic_inc() -> 1
  mutex_unlock()

So thread A has acquired the ref->active_count but since the ref was
still active at the time, it did not initialise it. By switching the
check inside the mutex to an atomic increment only if already active, we
close the race.

drm/i915: Fix modeset locks in sanitize_watermarks()

We've added more internal things that use modeset locks and
thus we need to be prepared for intel_atomic_check() grabbing
more locks than what our initial drm_modeset_lock_all_ctx()
took. So we're missing the backoff handling here.

Also drm_atomic_helper_duplicate_state() works against us
by clearing state->acquire_ctx in anticipation of
drm_atomic_helper_commit_duplicated_state() being used to
commit the state.

We could probably just reset acquire_ctx back, but instead
let's just rewrite the whole thing without using either of
those "helpers". There's also no need to add any connectors
to the state here since we just want the new watermarks
which don't depend on connectors.

drm/i915: Fix inconsistance between pfit.enable and scaler freeing

Despite that during hw readout we seem to have scalers assigned
to pipes, then call atomic_setup_scalers, at the commit stage in
skl_update_scaler there is a check, that if we have fb src and
dest of same size, we stage freeing of that scaler.

However we don't update pfit.enabled flag then, which makes
the state inconsistent, which in turn triggers a WARN_ON
in skl_pfit_enable, because we have pfit enabled,
but no assigned scaler.

To me this looks weird that we kind of do the decision
to use or not use the scaler at skl_update_scaler stage
but not in intel_atomic_setup_scalers, moreover
not updating the whole state consistently.

This fix is to not free the scaler if we have pfit.enabled
flag set, so that the state is now consistent
and the warnings are gone.

v2: - Put pfit.enable check into crtc specific place

prominent. With the removal of struct_mutex, this is not as important

Add convenience helpers for the most common uncore operations with
struct drm_i915_private * as context rather than struct intel_uncore *.

The goal is to replace all instances of I915_READ(),
I915_POSTING_READ(), I915_WRITE(), I915_READ_FW(), and I915_WRITE_FW()
in display/ with these, to finally be able to get rid of the implicit
dev_priv local parameter use.

The idea is that any non-u32 reads or writes are special enough that
they can use the intel_uncore_* functions directly.

v2:
- rename the file intel_de.h
- move intel_de_wait_for_* there too
- also add de fw helpers

drm/i915: Balance prepare_fb/cleanup_fb

intel_prepare_plane_fb() bails early if there is no fb (or rather
no obj, which is the same thing). intel_cleanup_plane_fb() does not.
This means the steps performed by intel_cleanup_plane_fb() aren't
balanced with with what was done intel_prepare_plane_fb() if there
is no fb for the plane. These hooks get called for every plane in
the state regardless of whether they have an fb or not.

Add a matching null obj check to intel_cleanup_plane_fb() to restore
the balance.

Note that intel_cleanup_plane_fb() has sufficient protections
already in place that the imbalance doesn't cause any real problems.
But having things be in balance seems nicer anyway, and might help
avoid some surprises in the future.

drm/print: introduce new struct drm_device based WARN* macros

Add new struct drm_device based WARN* macros. These are modeled after
the core kernel device based WARN* macros. These would be preferred
over the regular WARN* macros, where possible.

These macros include device information in the backtrace, so we know
what device the warnings originate from.

Knowing the device specific information in the backtrace would be
helpful in development all around.

While we do flush writes to the vma before unbinding (to make sure they
go through the right detiling register), we may also be concurrently
poking at the GGTT_WRITE bit from set-domain, as we mark all GGTT vma
associated with an object. We know this is for another vma, as we
are currently unbinding this one -- so if this vma will be reused, it
will be refaulted and have its dirty bit set before the next write.

4 years agodrm/i915: Don't use VBT for detecting DPCD backlight controls
Lyude Paul [Fri, 17 Jan 2020 23:21:54 +0000 (18:21 -0500)]
drm/i915: Don't use VBT for detecting DPCD backlight controls

Despite the fact that the VBT appears to have a field for specifying
that a system is equipped with a panel that supports standard VESA
backlight controls over the DP AUX channel, so far every system we've
spotted DPCD backlight control support on doesn't actually set this
field correctly and all have it set to INTEL_BACKLIGHT_DISPLAY_DDI.

While we don't know the exact reason for this VBT misuse, talking with
some vendors indicated that there's a good number of laptop panels out
there that supposedly support both PWM backlight controls and DPCD
backlight controls as a workaround until Intel supports DPCD backlight
controls across platforms universally. This being said, the X1 Extreme
2nd Gen that I have here (note that Lenovo is not the hardware vendor
that informed us of this) PWM backlight controls are advertised, but
only DPCD controls actually function. I'm going to make an educated
guess here and say that on systems like this one, it's likely that PWM
backlight controls might have been intended to work but were never
really tested by QA.

Since we really need backlights to work without any extra module
parameters, let's take the risk here and rely on the standard DPCD caps
to tell us whether AUX backlight controls are supported or not. We still
check the VBT, just so we can print a debugging message on systems that
advertise DPCD backlight support on the panel but not in the VBT.

Changes since v3:
* Print a debugging message if we enable DPCD backlight control on a
  device which doesn't report DPCD backlight controls in it's VBT,
  instead of warning on custom panel backlight interfaces.
